A. Magnetic force on a moving charged particle is always non-zero.
B. Magnetic force can change kinetic energy of a charged particle.
C. Magnetic force can change linear momentum of a charged particle.
D. A charged particle at rest does not feel magnetic force on it.
The correct statement(s) is/are
Solution:
Magnetic force is perpendicular to velocity, so it does no work and KE remains constant. It can change the direction of velocity (and thus momentum). For a particle at rest (\(v = 0\)), magnetic force is zero.
